BEFORE SWITCHING ON THE POWER

1. Detectors (or key switches) can be connected in two ways:

Conventional: One zone each is required for both tamper and the alarm. Both zones should be

closed with an end-loop resistor (4.7 kOhm). Program the ‘zones’ menu as

‘Alarm’

Dual loop: The alarm and tamper are placed together in one zone. The zone has two end-loop

resistors (4.7 kOhm) to differentiate between alarm and tamper. Figure 2 shows how

they are connected. Program the ‘zones’ menu as ‘Dual’.
